SARS-CoV-2 spike protein

New COVID-19 nasal spray outperforms current antibody treatments in mice

April 14, 2022
A new protein-based antiviral nasal spray developed by SQI member Michael Jewett and colleagues at Northwestern University, University of Washington and Washington University at St. Louis is being advanced toward Phase I human clinical trials to treat COVID-19. Designed computationally and refined in the laboratory, the new protein therapies thwarted infection by interfering with the virus’ ability to enter cells. Notably, the top protein also neutralized all tested SARS-CoV-2 variants, something that many clinical antibodies have failed to do.
Macrophages and lymphatic cells

Lymphatics aid heart repair

April 5, 2022
Expression of a pro-lymphangiogenic growth factor after heart injury activates the lymphatic system, spurring leukocytes to help clear away dying cells, according to a study co-led by SQI member Guillermo Oliver and published in the Journal of Clinical Investigation. The findings cement the lymphatic system’s role in repair after heart attack and has both theoretical and practical therapeutic implications, the researchers said.

Mussels’ underwater glue inspires synthetic cement

March 15, 2022

Using a novel method to arrange molecules, researchers led by SQI member Nathan Gianneschi have created a material that outperforms the extraordinarily strong glue secreted by mussels. Their findings expand on how these protein-like polymers can be used as a platform to create new materials and therapeutics.

“The polymer could be used as an adhesive in a biomedical context, which means now you could stick it to a specific tissue in the body and keep other molecules nearby in one place, which would be useful in wound healing or repair,” Gianneschi said.

Tumors dramatically shrink with new approach to cell therapy

January 28, 2022

Researchers led by SQI member Shana Kelley have developed a new tool to harness immune cells from tumors to fight cancer rapidly and effectively.

Their findings, published in the journal Nature Biomedical Engineering, showed a dramatic shrinkage of tumors in mice compared to traditional cell therapy methods.

‘Dancing molecules’ successfully repair severe spinal cord injuries

November 11, 2021
Researchers led by SQI director Samuel Stupp have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries. In a new study published in Science, they administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk.
Michael Vincent

Meet the Researchers: Michael Vincent

October 28, 2021
Michael Vincent is a graduate student in biomedical engineering who is co-advised by Mark Johnson and SQI member Evan Scott. In this interview, Vincent discusses his primary projects in the Scott Lab and the work he is currently doing at Grove Biopharma, a startup based on technology developed in the laboratory of SQI member Nathan Gianneschi.

COVID-19 PCR tests can be freeze dried

June 10, 2021

Northwestern University researchers led by SQI member Michael Jewett have discovered that commercially available polymerase chain reaction (PCR) tests can withstand the freeze-drying process, making them shelf-stable for up to 30 days and 50 degrees Celsius (122 degrees Fahrenheit) without sacrificing sensitivity and accuracy. 

The new strategy could help ease logistical challenges, making the “gold standard” tests for COVID-19 more available to help schools, businesses and sporting events safely reopen. It also could be a particularly powerful option for low-resource settings that lack access to reliable electricity and refrigeration.
